Can Turnitin detect essays rewritten by AI humanizers like Grubby AI or TwainGPT?

In short, can Turnitin detect AI humanizer?

This post contains information updated in January 2025

If you are a student, you might have seen those advertisements on Instagram or YouTube that promise to write or rewrite essays that are completely undetectable by Turnitin. When you are pressed for time, you might be tempted to use these AI tools to write your essays. Believe me, you are not alone. After all, who wants to spend countless hours writing a paper that they are not going to remember a few days anyway. However, remember that Turnitin – the eagle-eyed watchdog of academic integrity – is catching up fast. The University of Minnesota (UMN) recently expelled a student for using ChatGPT on one of its papers.  So, before you hit that “submit” button, think twice about the risks involved.

The questions that concern most students is: Will you be caught if you use an AI humanizer like JennyAI, GrubbyAI, or TwainGPT to rewrite your essays?  

Short Answer:

Yes, Turnitin can easily detect AI generated or AI paraphrased work. In my research, Turnitin can detect text paraphrased by AI humanizers 90 out of 100 times. An experienced professor, on the other hand, can detect AI generated or AI paraphrased work 100 out of 100 times. Even if your college does not use Turnitin, you are likely to receive a very low grade as AI tools usually write substandard formulaic content.

So, take the risk of using AI humanizer only if:

• You are okay with getting low grades, AND
• You have a lazy professor who does not care about students using AI

Long Answer:

Now, let us get technical for a second. Do not worry, I have cut the jargon and used a language that is easy to follow for most students.

I have written it in a question-and-answer format so that it is easy for you to find answers to your specific questions.

How do ChatGPT or other AI tools write your essays?

ChatGPT writes content using advanced natural language processing (NLP). When you ask ChatGPT a question or give it a prompt:

• It analyzes your input for keywords, context, and tone.
• Using this information, it predicts the most relevant and coherent sequence of words that fit the context of your query.

 

How are ChatGPT written essays different from human written essays?

• Lack of creativity and original thought: ChatGPT merely recombines patterns and information from its training data. In contrast, human writers can bring unique, original thoughts, experiences, emotions, and cultural context to their writing. They can develop novel arguments, interpret nuanced ideas, and offer subjective insights. In other words, if you must score a high grade in your next essay, you should hire a human writer.
• Lack of depth and context: ChatGPT provides information based on general patterns in the data it was trained on but struggles with highly contextual or nuanced topics. So, if you are looking for assignment help with advanced subjects like Finance, Economics, or Business Management, you are better off hiring a human writer.
• Limited knowledge base: ChatGPT’s knowledge is limited to its training data and relies on patterns rather than a dynamic understanding of the world. In contrast, a human writer can constantly update his/her knowledge by reading latest articles on a topic and make connections between ideas. So, if your essay requires up to date information and facts and figures, you should consider hiring a human writer.
• Detectable by Turnitin: ChatGPT, and other AI tools, follow a predictable writing pattern in terms of sentence structure and word choices. This makes it easier for Turnitin or any AI detection tool to develop algorithms that can identify these patterns. In contrast, human written content will always pass Turnitin check. If you want complete peace of mind in your final essay, consider hiring a human writer.

 

Can Turnitin detect AI-generated essays?

Yes, Turnitin has advanced AI detection capabilities that identify patterns, sentence structures, and stylistic markers unique to AI-generated content. Its algorithms are specifically trained to flag text that lacks the nuances of human writing.

 

What are some other limitations of using ChatGPT?

OpenAI, creator of ChatGPT, has admitted that ChatGPT has the following major limitations:

• It is Not Always Accurate: It can generate plausible-sounding but incorrect or nonsensical answers.
• No Memory Across Sessions: It does not retain conversations or knowledge of past interactions.
• Repetitive Patterns: For less specific prompts, it may generate repetitive or generic responses.

 

What will happen if I use ChatGPT to write my essays?

Unless your university specifically allows AI generated work, you will be flagged for plagiarism and likely receive F grade in your course. In extreme circumstances, you might be expelled from the institute for violating its academic integrity policy.  

Even if you your university (or professor) allows you to use ChatGPT, you will receive a low-quality work without any originality, depth, or personal touch. Based on my experience, these essays barely score anything above a D grade (barely PASS).

If you must maintain your grades for scholarship or to boost your resume, consider hiring a real writer.

 

Can I safely use ChatGPT if my university does not have Turnitin or similar software?

Even if your university does not have Turnitin, you have two major issues:

• An experienced professor can detect machine written work: Even though ChatGPT has gotten increasingly sophisticated, an experienced professor can still identify content that is not written by a human. They have years of experience reading human written papers and they can easily identify when a paper does not sound human-written. If your professor is the strict type, he/she might flag you for plagiarism and subject your essay for AI detection using freely available tools, which might land you in trouble.
• Risk of a low or failing grade: As ChatGPT mostly produces low-quality, formulaic content, you are at risk of getting a low grade or even a failing grade. Read on to find why ChatGPT fails in most tasks at undergraduate and postgraduate level.

 

How do AI humanizers like GrubbyAI or TwainGPT work?

AI humanizers like GrubbyAI or TwainGPT will merely paraphrase your essay by using a different set of patterns, which are once again predictable and easily identifiable by Turnitin’s algorithm.

 

Can Turnitin detect content that is rewritten by AI humanizers like GrubbyAI or TwainGPT?

Turnitin has an advanced algorithm that can identify both AI generated and AI paraphrased content. While humanizers like JennyAI or GrubbyAI rewrite text to appear unique, the core ideas and patterns often remain similar to the original, which Turnitin can flag. So, no matter which AI humanizer do you use, it will always be flagged by Turnitin and put your academic career at risk.

 

What are the other risks of using AI humanizers like GrubbyAI or TwainGPT to write my essays?

Besides the risk of being flagged for plagiarism, you run the risk of submitting an essay that does not make any sense. Your essay will lack any contextual understanding of what is taught in your classroom or asked in the essay requirements. It will consist of  generic content that fails to integrate any theories or concepts taught in your classroom. Further, it will lack any coherence between paragraphs or what it is trying to convey. So, think twice before you rely on such AI tools to write your essays for you.

How accurate is Turnitin’s AI detection?

Turnitin’s AI detection is reported to be highly accurate, identifying AI-generated or humanized text around 98% of the time. Even though no AI detection tool is 100% foolproof, most universities rely on Turnitin to flag students for plagiarism. If you are caught by Turnitin, you will be subject to additional investigation. The onus is on you to prove that the essay was indeed written by you.

 

Can I rely on AI tools like GrubbyAI or TwainGPT without being caught?

Using AI tools is a gamble. While some students might avoid detection temporarily, the risks are increasing as detection tools become more sophisticated. Additionally, keep in mind that professors are often adept at recognizing AI-generated work.

 

How do professors identify AI-written essays?

Professors can spot AI-written essays by looking for generic arguments, inconsistent tone, or ideas that do not align with class discussions. They might also use tools like Turnitin to confirm their suspicions.

 

Is using AI tools or AI humanizers cheaper than hiring a writing service?

While AI tools might seem cheaper, they often require additional time and effort to fix inaccuracies or improve quality. If you do not want to spend hours rewriting your AI written essays, you should consider hiring a professional writing service instead. A professional writing service provides customized, high-quality content without the risks of detection.

I have over 15 years of experience advising students on essays, assignments, dissertations, and quizzes. As an academic advisor, I work with hundreds of college professors across the US who use Turnitin to detect AI in their students’ work. I frequently talk to them about how they detect AI in their essays, how reliable AI humanizers are, and how strictly they deal with AI written work. My answer is based on my own research on different AI humanizers and my conversations with college professors.
